No (the event took place in Norway). I have only hearsay information from internet forums where someone commented that a NOTAM was not required for paraglider winching prior to this event, but the regulatory agency changed the rule consequent to this event.

Since I have no experience with winching, the concept of an errant airplane running into a winch cable is new to me and therefore interesting. It's not something that is often mentioned.

You have experience with winching and therefore see the event from a completely different perspective. Your matter-of-fact comment that errant airplanes commonly enter winch zones was also interesting to me.
